5 Claims.

My invention relates to improvementsin detergent dispensers and particularly to an improved system whereby detergent in solution may be fed through passageways which it is desired to clean 5 such as the interior passageway through tubes,

coils or other passageways.

An object of my invention is to provide a simple inexpensive structure which may be connected with a suitable source of water supply to feed detergent into a stream of water in such a manner that the detergent will be in solution and will pass at a substantially uniform rate of strength throughout the parts which it is intendedto clean.

Another object is to provide a construction for carrying out the purpose of my improvement which construction is of a small portable character and may be readily secured to and supported by the outlet faucet of an interior passageway which is intended for cleaning.

Another object is the provision of a detergent dispenser wherein the detergent which is to be placed in solution is carried in a porous puncturable bag-like container which is normally closed and which is adapted to be so disposed that water is discharged into the body of the detergent to carry detergent in solution through the mesh wall of the container into a larger water container which forms a part of the liquid stream and from which the detergent in solution is carried to the place where it is to do its work.

An important feature is that in the construction provided there is a water discharge tube which is adapted to be puncturably inserted into the interior of a mass of detergent carried in a bag-like container of the character described and which is provided with water discharge outlets suitably located to discharge water into the interior of the detergent mass within the bag and is provided with other water discharge outlets arranged above the bag to discharge water above the point of discharge of the detergent solution into the large container.

Various other features of merit will appear more fully from the following description, appended claims and accompanying drawing wherein,

Fig. 1 is a vertical sectional View through a device embodying my invention,

Fig. 2 is a vertical sectional view through the discharge end of the liquid outlet tube,

Fig. 3 is a schematic elevation showing the inclusion of my improvement in system.

In the cleansing of many articles such as coils 'and other similar small interior labyrinthian compartments it is diflicult to obtain satisfactory cleansing due to the inaccessibility of the surfaces to be cleaned. Different methods have heretofore been employed. One of them contemplates the use of passing steam through the system. Another method contemplates the passing 5 of detergent in solution through the system. In the use of chemical detergents one disadvantage which has attended their employment is the difficulty of insuring that all the detergent will pass into the solution. It has heretofore been found that the detergent frequently passes through with the liquid partly in solution and partly in lumps and chunks which did not fulfill their cleaning function. I

I have provided a system and mechanism which is intended to remove this difliculty. I provide a detergent dispenser in the form of a liquid container which has a removable cap 12 that fits thereover as shown in Fig. 1. This cap is cored out to receive a liquid tube 14 which empties into a rigid discharge tube 16 that is provided with a sharpened end portion 18. This discharge tube 16 is provided with a series of'liquid discharge outlets 20 adjacent to its sharpened end and a liquid discharge outlet 22 spaced from the first mentioned liquid discharge outlets.

The cap is also provided with a second cored out passageway 24. This is an outlet passageway for liquid from the container 10. It terminates in an enlarged passageway 26 located within a compressible gasket portion 28 which is adapted to fit snugly over the discharge end of a faucet 30 as shown in Fig. 3. In Fig. 3 the faucet 30 is shown as communicating with a coil 32 which is to be cleaned. The snug engagement of the portion 28 with the end of the faucet serves to support the entire assembly including the container 10.

Detergent of suitable characteristics is put up in sealed containers of a bag-like structure 34. These containers may be formed of suitable porous fabric mesh. The detergent itself is indicated as 36. This bag of detergent is impinged upon the sharpened discharge tube as shown in Fig. 1 and the water which escapes through the outlets 20 carries with it detergent in solution. This detergent must pass through the coarse fabric mesh bag and therefore this detergent must be in solution and cannot pass out in chunks or lumps.

The upper discharge outlets for liquid discharge the water into the main container above the bag. The detergent which enters the solution in the main container must therefore pass through this water which is being discharged into the upper portion of the main container to pass out through the outlet into the faucet and through the coil. I therefore provide that all the detergent which enters the coil should be in solution and further tend to maintain the concentration at a substantially uniform point so that the cleansing fluid which passes through the coil l e o a un i rm n en rat on a d will be completely in solution. It is apparent that when the detergent has been completely utilized the bag may be removed and another bag posi tioned as shown to carry on or repeat the operation.

What I claim:

1. A detergent dispenser comprising a liquid container, means for delivering liquid into said container including a rigid discharge tube having a sharpened end and provided with liquid discharge outlets disposed adjacent to said end and provided with other liquid discharge outlets ac d su st ntia ly away-f om said end, a liq solution outlet tube leading away from the top of said container, and a closed porous puncturable bag like container filled with detergent and s cured up n sa d ri id d schar tu ov ring said first mentioned liquid discharge outlets and paced lowsaid se nd m nti ned dischar utlet 2. A detergent dispenser comprising a liquid container, means for delivering liquid into said container including a rigid discharge tube having a cutting end and provided with liquid discharge outlets disposed adjacent to said end and provided with other liquid discharge outlets spaced substantially above said first outlets, said tube depending Within said container with the cutting end disposed in proximity to the bottom of the container, 2, liquid solution outlet leading away from the top of said container, and a closed porous puncturable bag like container filled with detergent and secured over said rigid tube by puncturably inserting the tube through the wall of the bag like container into the interior thereof to a distance suihcient to bring the first mentioned discharge outlets into the mass of the detergent within the bag like container.

3. A detergent dispenser comprising, in combination, a liquid container, means for delivering liquid into said container including a liquid discharge tube depending thereinto and provided with two liquid discharge outlets one spaced subs entia y a e the other, a l quid s lution utlet tube leading away from said container, and a closed porous puncturable bag like container filled with detergent secured over the end of said discharge tube with the discharge tube inserted through the wall thereof into the mass of detergent contained therein and with one of the liquid discharge outlets aforesaid disposed within the body of the detergent in the bag and the other liquid discharge outlet aforesaid disposed above said bag and between the same and the outlet from the liquid container.

4. A detergent dispenser comprising a liquid container, a liquid discharge conduit leading into said container and terminating therein in a rigid outlet tube provided with a sharpened end and having a liquid discharge outlet arranged adjacent to said end, a liquid solution conduit leading away from said tube, and a porous puncturable detergent carrying bag secured over the end portion of said tube by punctura-ble insertion of the sharpened end of the tube through the wall of the bag to a depth sufficient to bring the discharge outlet of the tube within the bag.

5. A detergent dispenser comprising a liquid container, a liquid discharge conduit leading into said container and terminating therein in a rigid outlet tube provided with a sharpened end and I.

having a liquid discharge outlet arranged adjacent to said end, a liquid solution conduit leading away from said tube and a porous flexible puncturable detergent filled bag puncturably inserted over the sharpened end of the tube and. supported upon the bottom of the container spaced from the side wall thereof.
